"How long have you been here?"
"Hmm, maybe... half an hour?"
Kaito Sora fell silent for a few seconds.
Finally, he decided to lie back on the pillow and picked up his phone from the nightstand, casually scrolling through it.
Not being rejected,
Suou Yuuki secretly breathed a sigh of relief.
Truthfully, she hadn't fully made up her mind about what to do.
According to her initial plan,
The earliest,
She would wait for a time when Rin Tohsaka wasn't around.
Find an opportunity.
To transition from being a cute little sister to a sneaky little cat.
Last night, when she barged into the bathroom,
She thought she had found the perfect opportunity with Rin not around.
But then...
The image of Sakura Tohsaka, covered in frost, flashed through her mind.
Suou Yuuki felt a wave of caution.
She had thought she was quick enough, but she never expected the tiny Tohsaka household to have someone even faster and bolder than her.
With Sakura already setting the precedent,
Simply copying her wouldn't leave much of an impression on Kaito Sora.
So...
After about the time it takes to drink a cup of tea,
Suou Yuuki pounced into Kaito Sora's arms, complaining, "Onii-chan, it's so gross."
"Go rinse your mouth first."
Kaito Sora pushed her face away with a look of disgust.
"Onii-chan, you're disgusted with Yuuki!"
"Even though Yuuki stayed up all night for you, studying so hard."
Kaito Sora had to admit that Suou Yuuki was indeed very clever.
He had been teaching Rin for so long,
But Yuuki had learned faster just by watching movies.
"Even a tiger doesn't eat its own cubs."
"Go rinse your mouth, and I'll give you something good."
Hearing this, Suou Yuuki's eyes lit up. She immediately got out of bed and ran into the attached bathroom.
The sound of brushing teeth came from the bathroom.
Soon,
Suou Yuuki ran back, her face full of anticipation as she jumped onto the bed and into Kaito Sora's arms.
"Onii-chan, Yuuki brushed her teeth."
"Reward!!!"
Kaito Sora didn't hesitate either, wrapping his arms around Suou Yuuki.
"Hmm?"
Although she had guessed what Kaito Sora was going to do from his earlier comment about "tigers not eating their cubs," his directness still made Suou Yuuki's eyes widen in surprise.
But soon, the girl turned passive into active.
After a while,
When they separated,
Suou Yuuki took a moment to catch her breath before eagerly trying to hug him again.
This was so much more interesting than eating her nephew!
But Kaito Sora pushed her away.
"Onii-chan?"
Suou Yuuki's eyes were filled with longing as she looked at him pitifully.
"Yuuki wants more."
"Yuuki, I have an ability..."
Kaito Sora directly explained the Contract Kiss ability to her.
When he first saw this ability, he had planned to use it on Rin Tohsaka, as she was the most suitable candidate in the Tohsaka household.
The other women just didn't quite measure up.
But since Suou Yuuki happened to be here, biting him,
Kaito Sora decided to test whether this ability could not only grant him benefits from the contracted individual but also share his own abilities with them.
"The decision is yours."
"After all, our relationship hasn't reached that level yet."
"Whether you accept or not is up to you."
"Even if you refuse, I won't blame you."
Even if Suou Yuuki refused, Kaito Sora wouldn't be surprised.
After all, accepting the contract meant that the contracted individual's entire being would be under his control, effectively becoming his slave for life. Even in the closest of relationships, it would be hard to accept such a thing.
"Hmm, Yuuki understands."
"Yuuki's life was saved by Onii-chan, so everything about Yuuki belongs to Onii-chan. Yuuki will listen to everything Onii-chan says."
Without any hesitation, Suou Yuuki hugged Kaito Sora again.
After all,
She had no intention of ever leaving Onii-chan.
But just before their lips met, Suou Yuuki suddenly stopped.
"What's wrong?"
Kaito Sora asked, looking at Suou Yuuki, who was so close that he could feel her long eyelashes brushing against him.
"Onii-chan."
"Is Yuuki your first contractor?"
Seeing the mix of anticipation and nervousness in Suou Yuuki's eyes, Kaito Sora couldn't help but chuckle.
"Yes, Yuuki is my first contractor."
"Yay!"
Although she was sure she had interacted with Kaito Sora earlier than Sakura,
Suou Yuuki couldn't be certain whether Rin had done anything like this with him.
But it didn't matter.
She, Suou Yuuki, had successfully claimed Onii-chan's first "first time"!
"Onii-chan's first time belongs to Yuuki!"
Kaito Sora laughed. "Is that kind of first time really that important?"
"Of course it's important!"
"Don't boys all like pure girls?"
"Although the concept is a bit different, if Yuuki can claim Onii-chan's first time, even if something happens to Yuuki in the future, Onii-chan will remember Yuuki forever!"
After saying this,
Suou Yuuki actively hugged Kaito Sora again.
Kaito Sora didn't push her away this time and directly activated the ability.
The moment the ability activated,
Suou Yuuki felt an intense sense of unease, as if the other party was trying to take control of everything about her.
If she didn't resist now,
Her entire life
Would become Kaito Sora's "possession."
However, despite the lingering unease, if it was Onii-chan, she was sure he wouldn't harm her.
Suou Yuuki tried to immerse herself in Kaito Sora's embrace.
Soon,
With Suou Yuuki's cooperation, Kaito Sora successfully established the "contract" with her.
Suou Yuuki lay limply in Kaito Sora's arms,
Murmuring, "Onii-chan, Yuuki is yours now!"
"Onii-chan mustn't bully Yuuki."
Kaito Sora smiled and pinched her cheek, somewhat surprised that the first person to become so "intimate" with him was Suou Yuuki.
Even with Rin, he had prepared himself for the possibility of rejection.
After all, no one would want their entire being to be controlled by someone else. Putting himself in their shoes, he knew he would never agree to such a contract if Suou Yuuki or Rin proposed it.
The first person he had in mind for the contract was actually...
The image of that seductive purple figure from last night flashed through his mind. Kaito Sora shook his head and focused his attention on Suou Yuuki.
Feeling the contract between them,
Kaito Sora sensed that he now had complete control over Suou Yuuki.
Moreover,
As he had hoped,
This trait not only allowed him to gain some of the contracted individual's abilities,
But he could also share some of his own traits
With the contracted individual.
However,
A contracted individual could currently only receive one of his traits.
After some thought,
Kaito Sora decided to let Suou Yuuki choose for herself.
"Yuuki, I have these abilities."
"Pick one."
Kaito Sora didn't hide his abilities.
After establishing the contract,
Suou Yuuki's entire being belonged to him, effectively making her his "familiar." There was no possibility of betrayal.
Suou Yuuki listened quietly as Kaito Sora explained his abilities.
"Yuuki wants the Spirit Manipulation ability, is that okay?"
"Are you sure?"
Kaito Sora asked. "Right now, Innate Thunder Body is the best ability."
If Suou Yuuki had the Innate Thunder Body, and he taught her the Five Thunder Spell, her strength would quickly surpass even Yotsuya Miko's special physique.
"Yes, Yuuki is sure!"
"If it's the Innate Thunder Body, Yuuki won't have much time to train."
"There's family matters, school, Onii-chan, and anime..."
"Spirit Manipulation suits Yuuki better."
"But if Onii-chan wants Yuuki to get stronger, Yuuki will work hard to learn the Five Thunder Spell!"
Although Suou Yuuki's tone was lively and playful, her analysis was quite calm and rational.
Kaito Sora nodded. "If that's the case, then I'll give you Spirit Manipulation."
Unlike Yotsuya Miko,
Suou Yuuki was the sole heir of the prestigious Suou family.
She was destined to inherit the vast Suou family business and likely become a celebrity diplomat.
This meant
She couldn't—and wouldn't—have as much time as Yotsuya Miko
To devote to training.
Between her studies, extracurricular activities like piano and noble etiquette, and managing relationships,
She already had very little free time.
Expecting her to spend what little rest time she had on training in the Five Thunder Spell
Wasn't very realistic.
After Kaito Sora shared the Spirit Manipulation ability with Suou Yuuki,
The ability in the contract column
Turned gray, indicating it could no longer be shared.
"Does this mean each ability can only be given to one person?"
"Is this temporary or permanent?"
As Kaito Sora pondered this,
Suou Yuuki had fully accepted the Spirit Manipulation ability.
"Onii-chan, you're so good to Yuuki!"
The girl, now having tasted the sweetness, was moved and hugged Kaito Sora again.
Just then,
A gust of wind blew through the window.
The bedroom door slowly creaked open.
Standing at the doorway,
With her hand raised to knock,
Alisa froze as she saw the scene on the bed.
